ROBERT r. frau, or W'ILLMAR, i'arrnvnsora` DIRECTION SIGNAL.

Application filed July 24, 1922. v fSerial No. 577,150.

VT 0 all wkomz't may conceive.'-

Be it known that I, ROBERT F. PEAU, a citizen of `the United States, residing at lVillmar7 `in the. county of Kandiyohi and State of Minnesota., have invented new and useful Improvements in Direction Signals, of which the following is a specification. Y

This invention relates toa directional signal for motor vehicles, the general object of the invention vbeingy to provide means for indicating the intentions of the driver so that the drivers of vehicles in the rear will be cautioned that the car ahead isto change its direction or its speed.

Another object of the invention is to provide means whereby the device can be used during the day as well as at night.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts,

to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be Lhad to the `accompanying drawings wherein like characters denote like or corresponding partsthroughout the several views, and in which Figure 1 is a view of the rear part of an automobile showing my invention in use.

Figure 2 is anenlarged front view of the i device itself. v

Figure Sis a viewof the dial. Figure 4 is a rear elevation. Figure 5 is a side View of the automobile showing how the device is operated from thev 2 so as to form a casing for receiving theV inner member or dial 3, which is carried by the shaft 4, arranged 'to rotate in the casing. The shaft passes through the casing and its front end carries kthe pointer 5 and to its rear end'is secured the pinion 6. Secured to the yback of the rear member and slidably mounted thereon there is a rack bar 7 which is suitably supported and isreciprocated by the connections 8. The connections lead to the front of the vehicle as shown in Figure 5 of the drawings so that the device can be operated by the driver of the vehicle. As the pointer and dial 3 are `secured yto the `shaft 'they will beirotated in unison by the shaft. The rear member isformed with a reflector 9.and has a socket for an electric lamp 10 which is supplied with current from any suitable source. The outer member 1 is provided with a circular' opening 11 which is placed at one side ofthe `center and with an opening 12 which is located near the edge of tbecasing. The periphery of this inember is divided intoifspaces 13 ywhich contain different words and kwhich are differently colored. For instance, one spaceis colored orange and contains the word Cautiom the neXt space is red and has Ithe word Stop therein, the next onek is green and contains the word Pass,7 the next is gray and contains the words Turn'right the `next is green and contains theword Clearf the next is purple and contains thel word Back and the next is blue yand contains the word Blocked Adjacent the opening `12 the member is colored yellow.

rlhe inner dia-l vor member 3 contains a plurality of lenses 14 `which will register with the circular opening 11 during the rotation of the member and as the opening 11 isin front of thelamp the rays thereofwill pass through the lens 14 which is in register with the opening 11 and through said opening so that the color of they lens can be seen by the drivers behind. These lenses are colored with the same'colors as the spaces on the front of the casing are colored with, Y except one, which isof clear glass as this color is carried by a lens l5 on the pointer which will be over the Lopening 11 when the vehicle is to be turned to the left. thus the proper color will be signalled. This inner dial also has spaces of clear glass at its periphery which are opposite thelenses and these spaces contain the words which are duplicates of those on the outer dial and these words on the inner dial arerarranged opposite the lenses 14 which correspond in color with the color of the spaces on the .outer dialwhihcontain the same` words.

These spaces will register'with the opening 12 while the lenses 14 are registering with the opening 11. `Thus, it willbe seen, a certain warning word is associated with a certain color both on'thevouter dial vand on the inner dial.'y the color and word appearing through the openings in the outer dial when the lamp is lighted and thefpointer indicating the proper word and color on the outer dial foruse during the day.

soy

From the foregoing it Ywill be seen vthat a plurality "of Warning signals can heV given with this device so that the drivers in the y rear will know just `Whatthecar in front is going to do. As Willalso be seen boththe Warning color and the Wordv are illuminated.

yl desire'it to be understood' that I' may make changes in the construction and in the combination and arrangement of the several "parts, provided that such'changes fall vvithin the'scope of the appended claim.V '1

Having thus described my vinvention what I claim as new is A signal ofthe class descrihed comprising a, casing having a pair of openings therein, a. dial on the face of the casing having Warning symbols thereon, a rotary member in the casing having colors and symbols thereon for .appearingA at the openings, a pointer associated With theV dial, meansfor moving the rotary member'and-theypointer simulthe same symbol as appearsrin the opening and means for illuminatingvthe Warnings on the rotary member.
